  • Warm inflation on the brane 
    Cid M.A.; Del Campo S.; Herrera R. (2014-04-04)
    In this paper, warm inflationary models on a brane scenario are studied. Here we consider slow-roll inflation and a high-dissipation regime in a high-energy scenario. General conditions required for these models to be ...
  • Warm inflationary model in loop quantum cosmology 
    Herrera R. (2014-04-04)
    A warm inflationary universe model in loop quantum cosmology is studied. In general we discuss the condition of inflation in this framework. By using a chaotic potential, V(φ) φ 2, we develop a model where the dissipation ...
  • Wastewater treatment and carbon trade: Impact of certified emission reduction in a biogas project 
    Chamy R.; Reyes P.; Vivanco E. (2014-04-04)
    Anaerobic digestion development has been marked by a constant evolution. Initially it was born as an efficient way to solve environmental problems, but later, a more comprehensive vision was adopted with the inclusion of ...
  • Water masses in the Humboldt Current System: Properties, distribution, and the nitrate deficit as a chemical water mass tracer for Equatorial Subsurface Water off Chile 
    Silva N.; Rojas N.; Fedele A. (2014-04-04)
    Three sections are used to analyze the physical and chemical characteristics of the water masses in the eastern South Pacific and their distributions. Oceanographic data were taken from the SCORPIO (May-June 1967), PIQUERO ...
